Sorry it took me so long to get back as I was sidetracked.
Here is what I get when I code it with my Fanuc 6T lathe generator (which I've attached).
N45 G01 X4.909 Z-1.0472
N46( SEMI-FINISH ID TO 4.971 DIAMETER )
N47 G01 Z-10.25
N48 G01 X4.917
N49( NEXT MOVE BORES ID TO 4.9790 DIA )
N50 G01 Z-11.19
Did you only change element 34's offset to none? If so, then maybe it's a setting in my .smf file (I always code the center of the tool tip).

A lathe G01 plunge in move is coded as a G02 move?
I tried your suggestion and at first glance it looked
liked it had worked.
However closer scrutiny reveals when going from left comp
to no comp
the insert goes on the diameter and cuts the element using
the
center of the insert and instead of being comped to one
side.

N0490X4.971 Ãthis
should be X4.917 diameter.( .054â difference. .054/2=.027+.004=.031

A lathe G01 plunge in move is coded as a G02 move?
Iâve attached a .SH2 lathe file along with its coded
file and its job setup file for a horizontal
lathe using a Fanuc 6T General Electric control. Early
80âs vintage stuff.
Hopefully the files will make it through.
If they do my question isâ
On T15 element 34 in the shape file I have the boring
bar plunging in .004â per side.
This is the code that SC generates for that .004â plunge
in move.

N0480Z-10.25
N0490G02X4.917Z-10.2652I0.031 Ãwhy
do I get this?
N0500( NEXT MOVE BORES ID TO 4.9790 DIA )
N0510G01Z-11.19
Why does SC output a G02 move for the .004â plunge in
move?
For manual editing at the machine control due to taper
problems
it is easier, and a lot less error prone to have a G01
move like soâ
N0460G01X4.909Z-1.0472
N0470( SEMI-FINISH ID TO 4.971 DIAMETER )
N0480Z-10.25
N0490X4.917
Ãthis line should be G01
N0500( NEXT MOVE BORES ID TO 4.9790 DIA )
N0510G01Z-11.19
Any reasons why this occurs?
I do not have V11.5 lathe so I cannot see whether or not
it happens when
coding with that package.
I am using the center of the rad on the insert tip, not
the virtual tip
because that is my customerâs request.
